The evolution of knowledge, and its representation in classification systems

Abstract

Classification systems are often described as stable reference systems. Produced by institutions such as libraries (LOC) or expert consortia (UDC), bibliographic classifications are also seen as external intervention into the autonomous, self-organizing system of knowledge production. Sometimes they are accused of being inflexible concerning the coverage of new ideas and scientific fields. Sketched as slow to change and cost-intensive to maintain, the question has been raised whether these classification systems are needed at all. Today, one of the most frequently raised questions is whether it would be better (e.g., more cost-efficient) to replace the classification systems with folksonomies or the 'wisdom of the crowd'?
